In July, Lennox International Inc. issued a voluntary recall for its Natural Pig Ears because they might be contaminated with salmonella, posing a risk to both humans and dogs. At least 93 people in 27 states were infected with salmonella linked to the pig ears, the CDC reported.

Some dogs may have salmonella infection but may not look sick. Dogs with a salmonella infection usually have diarrhea that may contain blood. Affected animals may seem more tired than usual, and may have a fever or vomit.

If your dog or cat has these signs of illness or you are concerned that your pet may have salmonella infection, please contact your pet’s veterinarian.
